House Peake of Starpike is a noble house from Starpike in the Reach. They blazon their arms with three black castles on orange.[1][2][3] The three black castles on their arms symbolize the three castles that House Peake once owned: Starpike, Dunstonbury, and Whitegrove.[4] Their motto has yet to appear.

The Peakes were historical rivals with House Manderly.[4] During the reign of the Gardener kings in the Reach, King Gwayne the Fat persuaded Lords Manderly and Peake to accept his judgment on their quarrel and do fealty for their lands, without having to fight a single battle.[7]

Near the end of the long reign of King Garth Greybeard, a problem arose with the succession as Garth had sired no sons and only daughters, one of whom had married Lord Manderly, and another to Lord Peake. Both lords were determined that their own wife should succeed to the throne, and the rivalry between them was marked by betrayal, conspiracy and murder, and finally escalated into open war with other lords joining the cause on both sides. The anarchy that followed lasted almost a decade until Ser Osmund Tyrell, the High Steward of Highgarden, made common cause with the other lords of the Reach and defeated both the Peakes and Manderlys. Ser Osmund then placed a distant cousin of the late Garth Greybeard on the throne who ascended as King Mern VI Gardener.[4]

House Manderly was driven into exile from the Reach by Lord Lorimar Peake upon the behest of King Perceon III Gardener who feared the Manderly's swelling power in the Reach.[8] This allowed House Peake to acquire the Manderly's seat of Dunstonbury.[8]
